| COMMERCIAL LASERS High-Power 10 W 9xx nm Fiber-Coupled Diode Laser 6398-L4 Series Key Features * 10 W output power * High reliability * 105 m aperture * 0.22 or 0.15 NA Applications * Fiber laser pumping * Material processing * Graphic arts * Medical * Remote power generation * Pyrotechnic ignition JDSU 6398-L4 series diode lasers offer 10 W of power from a 105 m fiber. The L4 is a revolutionary platform based on a long history of existing fiber-coupled L2 and L3 packages, incorporating a highly reliable design into a scalable commercial product. L4 multimode pump modules offer high brightness, a small footprint and simplified thermal management by distributing the diodes (heat sources), allowing the use of either air- or water-cooled architectures with predictable high reliability. By leveraging existing manufacturing facilities around the world, JDSU is able to offer all necessary attributes in a cost-effective solution that is ideal for the laser pumping market.

Sample: L4-9891510-100B 6398-L4 SERIES User Safety Safety and Operating Considerations The laser light emitted from this diode laser is invisible and may be harmful to the human eye. Avoid looking directly into the diode laser or into the collimated beam along its optical axis when the device is in operation. CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT WILL INCREASE EYE HAZARD. Operating the diode laser outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with the component must be employed such that the maximum peak optical power cannot be exceeded. CW diode lasers may be damaged by excessive drive current or switching transients. When power supplies are used, the diode laser should be connected with the main power on and the output voltage at zero. The current should be increased slowly while the diode laser output power and the drive current are monitored. Device degradation accelerates with increased temperature, and therefore careful attention to minimizing the case temperature is advised. For example, life expectancy will decrease by a factor of four if the case is operated at 50C rather than 25C. A proper heatsink for the diode laser on a thermal radiator will greatly enhance laser life. Firmly mount the laser on a radiator with a thermal impedance of less than 0.5C/W for increased reliability. ESD PROTECTION - Electrostatic discharge is the primary cause of unexpected diode laser failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling diode lasers. Labeling 21 CFR 1040.10 Compliance Because of the small size of these devices, each of the labels shown is attached to the individual shipping container. They are illustrated here to comply with 21 CFR 1040.10 as applicable under the Radiation Control for Health and Safety Act of 1968.
